Cabinet system and method of assembling the same

ABSTRACT

A front panel, a pair of side panels, a top panel, and a bottom panel connect to form a cabinet. Optionally, the cabinet includes a rear panel. Front panel includes a pair of master keyways and a pair of grooves. Each of side panels has a side key, a pair of side keyways, and a side notch. Each side key connects with one master keyway. Top panel includes a pair of top keys and a top extender. Each top key connects with one side keyway and top extender connects with one groove. Bottom panel includes a pair of bottom keys and a bottom extender. Each bottom key connects with one side keyway and the bottom extender connects with the other groove.

The present disclosure relates to a cabinet system used in kitchens or furniture design. Specifically, the present disclosure includes a front panel, a pair of side panels, a top panel, and a bottom panel that fit together to form a cabinet. Optionally, the cabinet can include a back panel or a rear panel.

Several techniques and systems have been developed for manufacturing and assembling cabinets. In a typical system, cabinet components are assembled using mechanical fasteners. In this type of system, often a skilled carpenter is required to assemble the cabinets, either in the manufacturing facility or at the final site of installation, for example a kitchen. The cabinets that are assembled in the manufacturing facility can be shipped in the assembled form to the final destination; however, this often requires large amounts of packing materials and shipping costs to do so. Unassembled cabinets can be shipped to the final destination, assembled, and installed at the final site of installation. However, these unassembled cabinets often require a skilled carpenter to assemble the cabinets which requires the homeowner to pay an additional cost of the carpenter to assemble and install the cabinets.

A cabinet device 20 is formed by assembling together front panel 22, right side panel 24, left side panel 26, top panel 28, and bottom panel 30. Optionally, a rear panel 32 is assembled onto cabinet device 20. Right side panel 24 is connected to front panel 22 by sliding side key 60 (FIG. 7) into master keyway 40 (FIG. 4) as shown in FIG. 1. Left side panel 26 is connected to front panel 22 by sliding side key 80 (FIG. 10) into the other master keyway 40 (FIG. 4) as shown in FIG. 1. Right side panel 24 and left side panel 26 are interchangeable to allow either panel to be assembled with either master keyway 40 (FIG. 4) of front panel 22. Top panel 28 is connected to front panel 22 by sliding each of top keys 100 (FIG. 13) into either of side keyway 58 (FIG. 8) of right side panel 24 or side keyway 78 (FIG. 1) of left side panel 26. Additionally, top extender 98 of top panel 28 fits into groove 42. Bottom panel 30 is connected to front panel 22 by sliding each of bottom keys 120 (FIG. 16) into the remaining side keyway 58 (FIG. 8) of right side panel 24 and the remaining side keyway 78 (FIG. 11) of left side panel 26. Bottom extender 118 of bottom panel 30 fits into the remaining groove 42. Top panel 28 and bottom panel 30 are interchangeable such that top panel 28 can fit in the location for bottom panel 30 and bottom panel 30 can fit in the location for top panel 28.

Optionally, rear panel 32 fits onto right side panel 24, left side panel 26, top panel 28, and bottom panel 30. In particular, one of back grooves 140 (FIG. 20) fits over or contacts side notch 62 (FIG. 7) of right side panel 24 and the other of back grooves 140 fits over or contacts side notch 82 (FIG. 10) of left side panel 26. Additionally, one of slots 138 covers or fits over upper portion 90 (FIG. 12) of top panel 28 and the other of slots 138 covers or fits over upper portion 110 (FIG. 15) of bottom panel 30. Rear panel 32 is configured such that it is reversible to the extent that either of slots 138 fits over either upper portion 90 (FIG. 12) or upper portion 110 (FIG. 15) and either of back grooves 140 (FIG. 20) fits over either side notch 62 (FIG. 7) or side notch 82 (FIG. 10).

In one embodiment, an adhesive is applied between side key 60 (FIG. 7) and master keyway 40 (FIG. 4) for both of the connections between right side panel 24 and front panel 22 and between left side panel 26 and front panel 22. In the same embodiment or another embodiment, adhesive is applied between each of top keys 100 (FIG. 13), side keyway 58 (FIG. 8), and side keyway 78 (FIG. 11), to attach top panel 28 to right side panel 24 and left side panel 26. Similarly, adhesive is applied between each of bottom keys 120 (FIG. 16), side keyway 58 (FIG. 8), and side keyway 78 (FIG. 11), to attach bottom panel 30 to right side panel 24 and left side panel 26. Adhesive can also be applied to top extender 98 (FIG. 12) and groove 42 (FIG. 5) to attach top panel 28 to front panel 22. Likewise, adhesive can be applied to bottom extender 118 (FIG. 15) and groove 42 (FIG. 5) to attach bottom panel 30 to front panel 22. Optionally, adhesive can be applied to each of slots 138 (FIG. 19), upper portion 90 (FIG. 12), and upper portion 110 (FIG. 15) to attach rear panel 32 to top panel 28 and bottom panel 30. In another form, staples, screws, or other fasteners can be used to attach each of slots 138 of rear panel 32 to top panel 28 and bottom panel 30. Also optionally, adhesive can be applied to each of back grooves 140 (FIG. 20), side notch 62 (FIG. 7), and side notch 82 (FIG. 10) to attach rear panel 32 to right side panel 24 and left side panel 26. Examples of adhesive are wood glue, carpenters glue, epoxy, or polyvinyl acetate (PVA), to name a few.
